Species Overview

Mojarra oreja azul

The bluegill is the most common sunfish in North America and often the first fish a young angler catches. Its deep body, dark ear flap, and iridescent blue-green colors make it easy to identify. A fierce predator of insects despite its small size.

Pez rojo

The goldfish was one of the first fish to be domesticated, with selective breeding in China dating back over 1,000 years. Despite common misconceptions, goldfish can live 10-15 years with proper care and require far more space than a small bowl.
